void main()
{
         int a=5;
         char str[0];
         str[0]=a;
         cout<<str[0];
}
Doesn't print 5, why.

Because you have assigned a binary 5 to str[0] and not the character '5'.  If you make the first assignment char a = '5'; then it should print '5'.

In declaring  
str[0]=a;
 you are saying input the character with the ASCII value of 5

If you use int
a='5';
and ouput a you will get 53 as ascii value of 5


Have a look at this ASCII table

I an writing a code which converts aaa to a3
Simlarly aaabbbbb as a3b5
This is why i need 5 to be appended in char array.

To convert the int to a char you can use

str[0]='0' + a;

It works by adding the ASCII value of char '0' to the integer digit.
